any one got any input or tried both looking for one for my 89

what type of riding do you do?

FMF gnarly has lots of low end, has little mid and no top end.
Pro circuit has no low end, lots of mid and some up top.
i use the stock. has quite a bit low, not as much as the FMF though. still has some mid, and more top end than you'd expect.

if you can find a fmf fatty it has killer bottom to top power, way better than gnarly or procuit

good luck finding a fatty... i havent seen one for a while.. That would have been my choice of pipe when i rebuilt the bike however since i ride alot of dunes and like the mid/top power i went with the PC Platinum.. Im hoping it performs well.. For the lost bottom end punch i just dropped a tooth on the front to help that out.

I'm having a gnarly reshaped to perform better than a fatty, I will let you guys know how it turns out.

Please do.. I was going to toss my gnarly but might just keep it if your idea works out
